The Woodford Models 65 and 67 commercial wall hydrants are the most specified commercial wall hydrants in the nation. They won’t freeze and drain automatically, even with a hose attached. They’re high flow and maintenance-free. They have fewer parts than other wall hydrants and are easily repaired. The Model 65 has a single-check vacuum breaker that is ASSE 1011 approved. The Model 67 features a double-check backflow preventer that is field testable to ensure the vacuum breaker is performing and is ASSE 1052 approved. All Woodford commercial wall hydrants are guaranteed for five years.
